Title: Detection circuit
Inventor: YAMAMOTO OSAMU
IPC: H02M7/08
Filed: 1986-02-08
Abstract: PURPOSE:To improve the linearity at a small signal region especially by providing an error amplifier, an inverse amplifier and two compensation diodes to the output of a conventional detection circuit so as to exclude the effect of the nonlinearity and temperature characteristic of the detection diode. CONSTITUTION:A high frequency voltage VRF is detected by a detection diode compensation diode X1 and inputted to the error amplifier A1. An output Vout of the amplifier A1 is fed to the compensation diode X2, and an output of the inverse amplifier A2 whose gain is -1 is fed to a diode X3 similarly, and a voltage is produced across the resistor R2. When the gain of the amplifier A1 is sufficiently large, the output Vout is balanced at a point where the voltage across the resistors R1, R2 is equal. Thus, the obtained output Vout reaches the peak of the voltage VRF. Thus, the detection to the small signal is made accurately without being affected by the forward and reverse resistance of the diode. Moreover, the temperature fluctuation of the detection diode characteristic is eliminated.
